Abstract (en)
A substrate (12) for power electronics (100) mounted thereon, comprises a middle ceramic layer (120) having a lower surface (124) and an upper surface (123), an upper metal layer (121) attached to the upper surface (124) of the middle ceramic layer (120), and a lower metal layer (122) attached to the lower surface (124) of the middle ceramic layer (120). The lower metal layer (122) has a plurality of millichannels (125, 126) configured to deliver a coolant for cooling the power electronics (100), wherein the millichannels (125, 126) are formed on the lower metal layer (122) prior to attachment to the lower surface (124) of the middle ceramic layer (120). Methods for making a cooling device and an apparatus (10) are also presented.
